I bought salmon head, froze it for 2 days and now I'm staring at it wondering if I should feed this to Leila LOL!

I took out the gills because I'm sure it'll give Leila runny stools. Pork and beef organs tend to give her runny stools even though she loves them. So, do I feed the whole thing to her? She's use to eating whole smelts and pieces of trout and tilapia (no bones).
